Subject: [radeon] radeon_kick_out_firmware_fb() can deref NULL
Date: Fri, 14 Jan 2011 18:49:40 +0100 [thread overview]
Message-ID: <20110114174940.GA9168@begonia> (raw)
Hello,
In commit a56f7428d7534f162fbb089c5c79012bf38a7c29 [1], the result of
alloc_apertures() function call is used without checking for a possible NULL
result, which may happen, as seen in [2].
The latest commit [3] in the drm-fixes branch of the
linux/kernel/git/airlied/drm-2.6.git repo still has the issue.
